Halo 4 Spartan Ops Launch Trailer Previews Co-op Action

343 Industries has created yet another launch trailer for Halo 4. This latest video focuses on the new Spartan Ops mode that will be making its debut with the game.

"Spartan Ops" is a series of single-player or co-op missions starring the crew of the UNSC Infinity. The ship arrives on the mysterious Forerunner planet of Requiem and is soon attacked by both Covenant and Promethean forces. Fireteam Majestic, the ship's team of Spartans, must battle countless enemies as they explore the planet.

The story of the UNSC Infinity will play out over 10 episodes, each with 5 missions. The first episode will ship with Halo 4. The others will be released through Xbox Live after the game's launch.

343 previously released live-action and single-player campaign launch trailers. Maybe they'll release one for the competitive multiplayer, too, just to make sure everyone's ready for the game's worldwide launch next week.
